Moyle InterconnectorThe Moyle Interconnector

The Moyle Interconnector links the electricity grids of Northern Ireland and Scotland through submarine cables running between converter stations at Ballycronan More in Islandmagee, County Antrim and Auchencrosh in Ayrshire. The link has a capacity of 500MW.

Cable Installation at Currarie PortThe commissioning of the Moyle Interconnector marked a real watershed for the electricity consumers and economy of Northern Ireland. When it went into commercial operation in early 2002, it ended the isolation of Northern Ireland from the much larger electricity systems and markets of Great Britain and the European mainland, where interconnection of national electricity systems has been the norm for many years. It has made a major contribution to the drive for lower electricity prices in Northern Ireland, which has a history of high energy costs.

It now provides competition in the electricity market arrangements in Ireland and makes possible trading with our neighbouring market in Great Britain. The Moyle Interconnector transmission capacity is available for third party access, i.e. to anybody who wants to trade in electricity in either direction between Ireland and Great Britain or beyond.
